You discredit Lewis by suggesting someone who lost to him couldn't be considered a H2H monster. Most knowledgeable fans concede Vitali would have a good chance at beating any fighter in history H2H. So will you in time if you manage to grow up and dislodge your head from your ass.
Some dudes are racking their brains so hard that they can't come up with one word to describe his career, so they combine two words and go with that. I can almost hear them thinking.
It's absurd to say Vitali will be forgotten. Same goes for Wlad. They are important champions (not like Moorer, Rahman, Braddock, etc.) that have made noise in the division since 2000-2001. Their career will probably end in 2014-2015. 15 years. It's a significant amount of time. We can say that the Klits won't be forgotten; at least until the last part of this century.
